@roch. Sorry for making a blanket statement. I was speaking for the person who independently buys their own health insurance. None the less, it is important for people to understand what their coverage is 1) People whose former employer/union provide retirement healthcare benefits are dependent on what that entity negotiates in the future...and that could change over time (providers and doctors could exit their network)
2) If people are buying their own plan, then they are better protected getting Original Medicare with a supplemental/Medigap plan than an Advantage plan, because Advantage restricts them to a network and if they want to change to Original Medicare later, they may find it very difficult to find a Medigap plan that will accept them
